Issues with stuck cases?

[Bravo1]

I've been reloading for a few years now and wondered if anyone else has issues around ambient temperature when sizing.

I'm trying to deprime and size some nickle .223 brass I picked up from Wes and use my own lube formula of Liquid Heet and Lanolin.
I haven't had any issues in the past but recently, due to the heatwave, I've had numerous suck cases. So far I've had to scrap over 50 cases that got stuck.
Nothing has changed and I'm using the same lube as before.

However when I rub the cases by hand with Unique Case Lube, it runs fine.

Do you think trying to size 90 degree heat in my garage could be the issue?

I would think it is a heat issue for sure. If the Unique case lube is working, maybe stick with using that.
Might be the heat and lanolin mix is getting messed up in the hot temps? Maybe vaporizing off the Heat too quickly?

That could be it. Glad we're starting to get a cool down so that may make a difference.
I'll wait a few weeks to see if the temperature drops to reasonable levels.

But using the Unique one case at a time could take a while, especially since I picked up 500 cases!

Melt the unique in the microwave, pour 1/3 can into a bottle of 99% alcohol, attach sprayer.
Boil a can of water before use, remove from the stove, place bottle of alcohol and unique in there for 15 min. Shake well, and spray away
